“…The DBM method has been successfully applied to the study of fluid instability problems, and a series of research results and new insights are gained with its help [57][58][59][60][61]. Introducing the Van Der Waals (VDW) equation of state into the existing discrete Boltzmann BGK model for RTI systems and considering the contribution of the density gradient to the entropy and internal energy of the system, we can obtain the DBM model as shown in Eq.…”

“…Zhou et al [9] analyzed the RTI and the KHI in wide ranges of density ratio, viscosity ratio, and Reynolds (Re) number adopting the lattice Boltzmann (LB) method. [10,11] Chen et al [12] investigated the effects of initial perturbations on the RTI, KHI, and the coupled RT-KHI system by using a multiple-relaxation-time discrete Boltzmann model. Besides, some studies [13][14][15][16] also simulated these two instability phenomena and validated the mathematical model via them.…”

“…From the perspective of physical modeling, the DBM is approximately equivalent to a continuous fluid model plus a coarse-grained model describing TNE effects. In recent years, the DBM has been widely used in the numerical study of the RT instability in compressible fluids and has made remarkable progress [31][32][33][34][35][36][37][38][39][40]. For example, Lai et al, studied the impact of compressibility on the RT instability by using the DBM and found that the compressibility effect and the global TNE intensity exhibit opposite tendencies in the early and later stages of the RT instability [31].…”

“…Chen et al, studied the effects of interfacial tension, viscosity, and heat conduction on the 2-D compressible RT instability by using the DBM with the van der Waals equation of state [33]. Chen et al, used the DBM with multiple relaxation times to study the influence of the length of the morphological boundary and the TNE intensity on the complex configuration and dynamic process of the coupled Rayleigh-Taylor-Kelvin-Helmholtz instability system [34]. Zhang et al, studied the fine structure and various non-equilibrium behaviors of the RT instability flow near the interface in a miscible two-fluid system by using the compressible DBM with tracer, and discussed the effects of compressibility and viscosity on the RT instability mixing [35].…”
